100
A push or pull
What is force?
100
This simple machine is a flat surface tilted up or down at an angle.
What is an inclined plane?
100

This simple machine is keeping the can suspended in the air

What is a pulley?

100
The formula for calculating work.
What is force times distance equals work?
100
Work is measured by this unit.
What is a Joule?
200
The definition of distance is this.
What is how long, how far, or how tall something is?
200

This simple machine has a grooved wheel 

What is a pulley?

200

True of false: Machines can be useful even if they don't give mechanical advantage.

What is true?

200
Calculate the work for a force of 6 Newtons and a distance of 4 Meters.
What is 24 Joules? 6 x 4 = 24
200

True or false: The Joule is a unit for work AND energy

True

300
Distance is measured in this unit of measurement.
What is a meter?
300
This simple machine does work by pivoting on a fixed point called a fulcrum.
What is a lever?
300

True or false: The closer the fulcrum is to the load, the less the force required to move the load.

What is true?

300

In our class we used this instrument to measure force.

What is a newton meter or spring scale.

300

This is the force a simple machine puts out

Output

400

Scientists say this happens when a force is applied to an object and the object moves a distance.

What is work?

400

This simple machine is a special kind of inclined plane that helps by cutting or spreading apart

What is a wedge?

400

True or false: an inclined plane increases the force required to move a load.

What is false?

400
We can use this substance to reduce friction and use less force.
What is a lubricant?
400

This is the point where a lever rests and pivots on.

What is a fulcrum?

500

This is the name of the unit used to measure force with. The name is from the famous scientist who experimented with gravity.

What is a Newton?

500

This simple machine is a wedge with threads that can be used to hold things together. Or it can be thought of as an inclined plane wrapped around a cylinder.

What is a screw?

500

How can simple machines change force?

They change direction, speed, magnitude

500

If you were using a lever and you wanted to reduce the force needed to lift the load you could move the fulcrum. Where would you put it?

What is closer to the load?

500

This is the name of a machine that is made of more than one simple machine.

What is a compound/complex machine?
